Sam Icay – Executive Council – Member-at-Large

Coming SoonSam was born on the Upper Lake reservation in the “old farmhouse”, which has since been replaced by a private residence. He attended Upper Lake Grammar School and the Upper Lake Union High School graduating from both schools. He worked for a local trucking company which transported pears to Williams, California for railroad shipping. He decided to enlist in the US Navy to learn a trade as an aviation jet mechanic. After completing several Naval schools, he was assigned to the USS Yorktown, CVS-10, an aircraft carrier based out of Long Beach, California. He served three years as Ships Company working as an aircraft flight director. The rest of his career was assignments to aircraft jet attack squadrons and several more aircraft carriers. He was married and raised two children while in the Navy. This caused him to start thinking about a different career. He applied for the post office carrier position, Oakland Police Officer, San Francisco Police Officer and the California Highway Patrolmen positions. He was working at the Fallon; Nevada Naval gunnery range when he received a telephone call asking if he could report to the December cadet class. His discharge date was December 6th and he entered training on the 8th of December.

Upon graduating from the CHP Academy, his first assignment was the Contra Costa county office in Concord for 14 months. He voluntarily transferred to Solano county office in Vallejo and worked there for 3 1/2 years before his final assignment in Napa County in the city of Napa. He served in Napa for 25 years and worked in several special assignments. His most favored assignment was working as a motorcycle patrol officer. Even though he was involved in 6 accidents, luckily he did not incur any serious injuries. He retired on a disability due to an injury and served 29 years and 3 months as a highway patrolman. During this time, he attended Napa Jr. College and obtained enough credits to transfer to the Golden Gate University where he eventually obtained his BA in Administration of Justice.

He took a temporary position as a security person inspecting loads exiting a local lumber yard and that turned into a full time assignment. He served for 4 years, when the Tribe advertised for the Tribal Administrator position in 2000. He applied and served 3 ½ years as the Tribal Administrator before deciding to run for the Executive Council Member-at-Large position. It was the time when the tribe was looking for financing, Land into Trust, and economic development.

His desire is to have employment for all members, housing in the local communities and to see the tribe progress towards having a good living environment, education for the children and health care, to name a few of the important issues. We need to update our Constitution, Enrollment Ordinance and the Election Ordinance. With hard work and dedication, it can be achieved.
